Level 6
You're kind of comparing apples to oranges. You can do almost infinitely more with Laravel than you can with WP, but depends on your requirements and how much time/money you have.
In the 60 seconds I spent looking at airtasker on my phone, I'd say you'd be hard pressed to duplicate it on WP. However, do you have experience in Laravel, or have people with experience that will develop it for you? I can build a WP site in a weekend. On the other hand, I've spent 10-20 hours a week for the past 6 months on my own Laravel site and it's maybe 75% complete!
